Navtex/SitorB SHN Argentina 12579 kHz. Nautical Radio Announcements
I usually check the messages on the frequencies used by Argentina’s naval hydrographic services, and today the first two caught my attention:
Firing tests (I assume this is a military exercise)
Suborbital rocket launch test
The image in the post shows both notices in English. About 10 seconds into the video, the screen zooms in so you can read the original messages in Spanish more clearly.

@atake I only used that account for the marketplace (searching for vintage radios and other tech), following accounts related to our hobby, and posting in your group. That’s all I did. I don’t see what could be suspicious about that.

Hey! Hi!
I'll be back for sure, maybe with a new account if fb comes up with a solution. About two months ago, I got a notification that my account had been suspended for two weeks due to suspicious activity! I have no idea what that was all about. I filed a complaint but didn’t get a response. Now that the suspension period is over, my account is in read-only mode—I can only send messages, but I can’t do anything else. I’ll try again, and if I don’t get it back, I’ll create another account.

@2CynicAl65 There are days when I can hear them clearly from South America (Paraguay). They even send you eQSLs.
This one is on the same frequency; I have posts about other frequencies as well:

Yesterday I posted this on Reddit in case it helps anyone else who wants to try DWD RTTY with FLDIGI:
I was finally able to receive a clear RTTY signal from DWD. I could always see it, but I couldn't decode it because the signal was weak, and I also had a bit of trouble getting the FLDIGI settings right.
The limited information available online about the settings never worked for me. That is, until I read here that someone mentioned it worked for them by switching to CW mode in the SDR# and FLDIGI. And that worked for me.
I didn't get good reception with the MLA-30+, but the K-480WLA did the job.
FLDIGI configuration:
DWD 2 Pinneberg RTTY 11039 kHz
The video starts with the audible RTTY signal from DWD with SDR# and then the FLDIGI captured, zoomed in so you can see the text in the capture better. At the end, an image of the K-480WLA receiver module and the AirSpy HF+ Discovery.

Radio Ext. España 17715 kHz - Antenna comparison w/ the Standard C6500
When I recovered this radio, it worked fine with a long wire antenna, but when I tried the MLA-30+, the reception was very poor; it seemed to overload the radio. But I didn't worry about it, since the radio was working and that was enough.
Today I tried the K-480WLA, and it worked better than I expected.
The first 30 seconds of the video are with the standard wire antenna (16 AWG), approximately 30 meters long. You can hear some persistent background noise, but the reception is relatively clear.
The next 30 seconds are with the K-480WLA, and you can hear that it significantly reduced the background noise and improved the reception quality.
The last 15 seconds show how I made a basic connection to the Standard C6500. Now that I know it works, I'm going to build a custom connection for this device.

@joaocond78 I haven't been able to try it yet, I'll do it this weekend. I need to make some changes to the location where I want to place the antenna, and it will take me a little while.
New accessory for the hobby: K-480WLA
People speak very highly of this antenna and say it's perfect for listeners. And other users who have upgraded from the MLA-30 to this antenna say it's very superior.
Anyway, it's finally here, and this weekend I'll be doing the first tests—just as it is, with all its accessories and cables, without any modifications.
The post/thread includes photos of the box and I've added photos with translations of some parts. I also bought some TNC-to-F adapters so I could test them with the RG6 cables I use with F-type connectors.
